SpaceX Delivers Ice Cream, Mice, AI Robot to Space Station

The nearly 6,000-pound (2,700-kilogram) delivery includes genetically identical mice for a study of gut bacteria, and the round robot Cimon (pronounced Simon). Slightly bigger than a basketball, the AI robot from the Germany Space Agency is meant to assist German astronaut Alexander Gerst with science experiments. Cimon's brain will constantly be updated by IBM, so its intelligence -- and role -- keep growing.
